Product Description:

The MAC090C-0-KD-4-C/110A-0/WI522/S001 is an AC servo motor built by Bosch Rexroth Indramat for use in the MAC AC Servo Motors series. It is specified as a motor for analog drives, so it interfaces directly with velocity or current-mode amplifiers that rely on analog command voltages rather than digital network control. This arrangement suits motion systems that use established analog control architecture in packaging, handling, and general automation equipment. In automated lines, it supplies closed-loop torque and speed to positioning tables, pick-and-place axes, or spindle functions, maintaining accuracy by pairing the embedded tacho circuit with the drive electronics.

The unit has a centering diameter of 110 mm, allowing precise seating against gearbox or machine frames and helping maintain accurate shaft alignment during installation. Heat produced by the stator is removed through natural convection, so no external blower or liquid circuit is required. Under rated conditions, the rotor turns at 1500 rpm, a speed that pairs well with low-ratio gearboxes in moderate dynamic applications. Winding code KD identifies the coil resistance and inductance expected by the matching drive, which helps the amplifier regulate current correctly. The built-in tacho generator produces 3 V/1000 rpm, giving the controller a proportional voltage signal for precise velocity feedback during steady running and load changes.

For position or speed loop closure, the feedback channel includes tacho feedback with an incremental or absolute encoder, allowing the drive to use tacho data for speed regulation while also receiving encoder information for motion control. Velocity ripple stays within the limits of the standard tacho quality, which helps maintain smooth operation without extra signal filtering. Control wiring remains limited to power, tacho, and encoder lines, which helps the motor fit into existing cabinets with minimal changes to legacy analog drive layouts.
